The book in question is Sussex Folk Tales, written by professional storyteller Michael O’Leary. The article includes this passage (a summary rather than a direct quotation): There is also riveting folk tale about a mouth organist called Charlie Winnick who was supposed to have been one of the best players during the interwar years. But when he was young, he was a terrible player and bullied by some other children, who took his mouth organ and threw it into a field. Having scrambled through the field to find his mouth organ, he goes to sit and enjoy a quiet moment of reflection, but sees a scarecrow in the field in front of him move its arms. The scarecrow then flies him inside Mount Caburn, where the pharisees (Sussex dialect for fairies) teach him to play the mouth organ exquisitely. When he returns home the next day, the boys who bullied him have been given a good thrashing and his parents are relieved to see him. Of course they don’t believe his story about the pharisees but no one can deny his improved ability at the mouth organ.
